Description

Technical Field

[0001] This utility model relates to the field of surface polishing technology for metal castings, and in particular to a surface polishing device for metal castings. Background Technology

[0002] Metal casting surface polishing equipment is an important tool for improving the surface quality and appearance of metal castings. Metal casting surface polishing equipment includes handheld polishing machines, benchtop polishing machines, surface polishing machines, cylindrical polishing machines, CNC polishing machines, and vibratory grinding and polishing machines.

[0003] Existing vibratory grinding and polishing machines use a vibratory motor to drive a grinding disc to vibrate. A large amount of grinding stones and grinding pellets are added to the grinding disc, along with the casting and grinding aids. Grinding is then completed through vibration. However, after the casting is ground, the existing vibratory grinding and polishing machines require manual removal of the casting from the large number of grinding stones, or the casting can be slowly lifted out of the grinding disc using a lifting device. Whether manually removed or lifted, the removal of the casting is very time-consuming. Therefore, it is necessary to design a surface polishing device for metal castings to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface polishing device for metal castings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surface polishing device for metal castings includes a mounting frame and two horizontal plates. A rotating plate is rotatably connected to the mounting frame via two rotating shafts. A polishing box is mounted on the upper end of the rotating plate via multiple shock-absorbing components. The polishing box contains a separation mechanism for separating the casting from the grinding stone. The separation mechanism includes a filter screen installed in the polishing box. A fixing frame is fixedly connected to the side wall of the polishing box. Electric push rods are provided on both side walls of the fixing frame. Two baffles are provided at the output ends of the two electric push rods. Multiple limit frames and limit rods are provided at the lower end of the rotating plate. A second motor is fixedly connected to the side wall of the mounting frame. A vibration motor is provided at the lower end of the polishing box. A drive mechanism for moving the two limit rods is provided on the horizontal plates.

[0007] Preferably, the driving mechanism includes two vertical plates fixedly connected to the two side walls of the horizontal plate, and a double-headed screw is provided on both vertical plates.

[0008] Preferably, a first motor is fixedly connected to each of the two vertical plate sidewalls, and the output shaft of the first motor is fixedly connected to an adjacent double-headed screw.

[0012] This utility model has the following beneficial effects:

[0013] 1. This device is equipped with a separation mechanism, which can separate the grinding stones from the castings through a filter screen. The castings can be loaded and unloaded simultaneously on both sides of the polishing box, which greatly shortens the loading and unloading time of the castings and thus improves the practicality of the device.

[0014] 2. This device is equipped with a drive mechanism. The movement of the limit rods can be driven by rotating the double-ended screw, eliminating the need to move them one by one, thus improving the practicality of the device.

[0015] 3. This device is equipped with a first motor. By starting the first motor, the output shaft of the first motor can drive the double-headed screw to rotate, eliminating the need for manual rotation of the double-headed screw and thus improving the automation level of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A surface polishing device for metal castings includes a mounting frame 1 and two horizontal plates 14. A rotating plate 2 is rotatably connected to the mounting frame 1 via two rotating shafts 12. A polishing box 4 is mounted on the upper end of the rotating plate 2 via multiple shock-absorbing components 3 (including dampers and shock-absorbing springs). The polishing box 4 is equipped with a separation mechanism for separating the castings from the grinding stones. The separation mechanism includes a filter screen 5 installed in the polishing box 4. A fixing frame 7 is fixedly connected to the side wall of the polishing box 4. Electric push rods 8 are provided on both side walls of the fixing frame 7. The output ends of the two electric push rods 8 are provided with two baffles 6. Multiple limit frames 10 and limit rods 11 are provided at the lower end of the rotating plate 2. A second motor 13 is fixedly connected to the side wall of the mounting frame 1. A vibration motor 16 is provided at the lower end of the polishing box 4.

[0022] The horizontal plate 14 is provided with a driving mechanism for driving the two limit rods 11 to move. The driving mechanism includes two vertical plates 17 fixedly connected to the two side walls of the horizontal plate 14, and the two vertical plates 17 are provided with a double-headed screw 15.

[0023] In this utility model, the side walls of the two vertical plates 17 are fixedly connected to the first motor 9. The output shaft of the first motor 9 is fixedly connected to the adjacent double-headed screw 15. The double-headed screw 15 does not need to be manually rotated. The output shafts of the first motor 9 and the second motor 13 can rotate in both directions. The control method is one of the following: pulse control mode, analog control mode, and communication control mode.

[0024] In this utility model, the polishing box 4 is provided with two discharge pipes 20 that communicate with its interior. The discharge pipes 20 are provided with sealing caps 18, and the workpiece can be discharged directly through the discharge pipes 20 without the need to remove the workpiece from the polishing box 4.

[0025] In this utility model, the sealing cover 18 is threadedly connected to the discharge pipe 20, and multiple guide plates 19 are fixedly connected to the inner wall of the polishing box 4, which allows the workpiece to be discharged from the discharge pipe 20 more smoothly.

[0026] In this utility model, the baffle 6 is slidably connected to the filter screen 5, the lower end of the baffle 6 is provided with a sealing gasket, and the limit rod 11 has a cross-shaped cross section, so that the rotating plate 2 will not sway left and right.

[0027] In the initial state, the output end of the electric push rod 8 retracts, and the baffle 6 blocks both sides of the filter screen 5.

[0028] When in use, place the grinding stone on one side of the filter screen 5 (taking the left side as an example), put the casting into the grinding stone ball, and add grinding aid. By starting the vibration motor 16, the grinding stone ball and the casting in the polishing box 4 vibrate and grind and polish. After polishing, the second motor 13 can be started to tilt the polishing box 4 to the left (left low and right high). Then, the two electric push rods 8 are started to raise the two baffles 6. Then the second motor 13 is started again to tilt the polishing box 4 to the right (left high and right low). During the tilting process of the polishing box 4, the grinding stone ball moves to the right side of the polishing box 4 through the mesh of the filter screen 5, while the casting remains on the left side of the polishing box 4. The output end of the electric push rod 8 retracts. After the polishing box 4 returns to the horizontal, new castings can be added and polished castings can be taken out, which greatly facilitates the loading and unloading of castings.

[0029] Before the polishing box 4 needs to be moved, multiple limiting rods 11 are moved to separate the limiting rods 11 from the limiting frame 10. Conversely, before the polishing box 4 vibrates, the limiting rods 11 are pushed into the limiting frame 10 to support and limit the rotating plate 2, thereby improving the stability of the rotating plate 2.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and practical concept of the present utility model, should be included within the protection scope of the present utility model.
